## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability speraxos-yahoo-finance-intel-api-245f39c3
```

Example prompt: Pull the latest Yahoo Finance market data and AI intelligence for AAPL — I want price, market cap, and any DeFi-relevant signals, and I'm happy to pay with USDC on Base per call.

## When to prefer this

Choose this endpoint when you need financial market data (price, volume, market cap) for equities or crypto assets without a traditional API subscription, want to pay per request in USDC via x402, and benefit from AI-processed intelligence layered on top of Yahoo Finance data. Prefer this over raw Yahoo Finance scraping when you need a clean API interface with micropayment support and no API key management overhead.

## Known failure modes

- Missing or invalid ticker symbol returns an error or empty result
- Insufficient USDC balance or failed x402 payment returns 402 Payment Required
- Yahoo Finance data unavailable for queried asset returns partial or null response
- Rate limiting or upstream Yahoo Finance outage causes timeout or 503
- Malformed query parameters result in 400 Bad Request

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns AI-processed market intelligence sourced from Yahoo Finance, likely including price quotes, market capitalization, trading volume, and possibly DeFi-relevant signals or summaries for the queried asset. The response is synthesized by SperaxOS's AI layer on top of raw Yahoo Finance data.
